我正在尝试以 JSON 格式输出我的记录器,这样我就可以消除在我的 ELK 堆栈中使用过滤器的需要。它似乎确实有效。
这是我所拥有的
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.json.simple.JSONObject;
public class MyApp {
static Logger logger = LoggerFactory.getLogger(MyApp.class);
@SuppressWarnings("unchecked")
public static void main(String[] args) {
// TODO Auto-generated method stub
JSONObject obj = new JSONObject();
JSONObject obj2 = new JSONObject();
obj.put("name","foo");
obj.put("num",new Integer(100));
obj.put("balance",new Double(1000.21));
obj.put("is_vip",new Boolean(true));
obj2.put("ob2name","bar");
obj2.put("ob2num",new Integer(200));
obj.put("names", obj2);
logger.info("{}", obj);
}
}
输出到我的 file.log
{"@timestamp":"2016-07-27T17:51:08.331+01:00","@version":1,"thread_name":"main","logger_name":"MyApp","level":"INFO","level_value":20000,"HOSTNAME":"gman","message":"{\"names\":{\"ob2num\":200,\"ob2name\":\"bar\"},\"balance\":1000.21,\"is_vip\":true,\"num\":100,\"name\":\"foo\"}"}
输出到 logstash 控制台
{
"@timestamp" => "2016-07-27T16:51:08.331Z",
"@version" => 1,
"thread_name" => "main",
"logger_name" => "MyApp",
"level" => "INFO",
"level_value" => 20000,
"HOSTNAME" => "gman",
"message" => "{\"names\":{\"ob2num\":200,\"ob2name\":\"bar\"},\"balance\":1000.21,\"is_vip\":true,\"num\":100,\"name\":\"foo\"}",
"host" => "gman",
"path" => "C:\\apps\\dots\\logs\\file.log"
}
我的问题
该消息似乎以字符串形式输出,我如何将其输出为 JSON,以便 Elasticsearch 可以获取各个字段并将它们编入索引,以便它们可以被搜索?
